Hi and welcome to HCM. Thank you for your query.
Neurogenic shock? It can maybe prevent cardiogenic shock
. it is maneuver which facilitate blood flow from your extremities to your heart and then more important organs are better perfused. It is hard to say did this save your life but it probably helped if you had hypotension
when this happened. So you can be grateful to this man but i wouldnt say this saved your life. WIsh you good health.
